6. Operating Instructions

Unlocking the Door:

• Using Passcode: Enter your 1-15 digit passcode on the keypad, then press the '✓' (check) button. The lock will disengage, allowing you to turn the knob.
• Using Mechanical Key: Insert the mechanical key into the keyhole and turn to unlock.

Locking the Door:

• Auto-Lock: If enabled, the lock will automatically engage after a set period (programmable from 2 seconds to 12 hours).
• Manual Lock: Press any button on the keypad to manually engage the lock.

Special Modes:

• Guest Mode: Allows the door to remain unlocked for a specified period, ideal for visitors.

7. Programming Passcodes

The lock supports up to 50 personalized passcodes. Refer to the detailed programming instructions in the separate 'Remote Code User Guide' included in your package for specific steps on setting master codes, user codes, and temporary codes.

Anti-Peeping Technology:

To protect your passcode from onlookers, you can enter random digits before or after your actual code. The lock will only recognize the correct sequence of your passcode within the longer string of numbers.

Remote Code Generation:

The Richelock IU50B allows you to generate and share temporary dynamic passcodes remotely. This feature is useful for granting access to guests or service providers without needing to be physically present or relying on an internet connection or smartphone app.

8. Maintenance

Battery Replacement:

The lock operates on 2 AAA batteries, which typically last over a year. When batteries are low, the lock will provide an audible or visual alert. To replace, remove the interior knob assembly cover, replace the old batteries with new ones, ensuring correct polarity, and reattach the cover.

Emergency Power:

In case the batteries completely run out, you can use a Type-C cable to connect an external power bank to the Type-C port on the exterior assembly for temporary power to enter your code.

Cleaning:

Wipe the keypad and lock body with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.

9. Troubleshooting

• Lock not responding to keypad:
  • Check if batteries are correctly installed and have sufficient charge. Replace if necessary.
  • Ensure the cable connection between the exterior and interior assemblies is secure.
• Knob turns but door does not unlock:
  • This indicates the solenoid is not engaging. Re-check cable connections and battery power.
  • Ensure the spindle is correctly aligned and inserted into the latch mechanism.
• Passcode not working:
  • Verify the correct passcode is being entered.
  • Try resetting the lock to factory settings and reprogramming your passcodes (refer to the 'Remote Code User Guide').
• Lock is stiff after rain/extreme weather:
  • While designed to be weatherproof, extreme conditions can sometimes affect mechanical parts. Ensure the lock is properly installed and sealed. If issues persist, contact customer support.
